Abstract:
A spray nozzle comprises, in a housing, a hollow nozzle interior comprising a discharge chamber containing a nozzle outlet and, as a first stage of turbulence, an annular chamber coaxially about the central axis of the nozzle outlet, and feed channels which lead from the annular chamber at least approximately tangentially to the periphery of the discharge chamber, and supply duct means for feeding liquid to the first stage of turbulence comprising feed channels feeding liquid tangentially. The hollow nozzle interior further comprises at least one additional stage of turbulence, and between two successive stages of turbulence, at least one obstacle breaking up the liquid flowing from the upstream to the downstream stage of turbulence and deflecting the liquid out of the flow plane through the annular chamber towards the side of the nozzle outlet by an angle of maximally 90.degree..
Abstract:
Fuel is fed by a feeding pump to a pressurized container. A predetermined amount of fuel is kept constant in the container by a floater which carries a needle for opening and closing a return as required. In the pressurized container the fuel is kept by a compressor under compressed air pressure which may be regulated by a pressure control valve, so that when the valve is opened fuel and air both under the same pressure are pressed into a nozzle unit in which air is highly pressed in the fuel so that when it leaves the nozzle channel it expands in an explosive manner and bursts the fuel into fine droplets. Secondary combustion air from an air generator is blown into the flame perpendicularly to the axis of the flame and fed to the fuel-air mixture.
Abstract:
The device comprises a treatment cylinder (1) into which one extremity (E) is placed for treatment of a peripheral circulatory disorder and subjected to hyperbaric and hypobaric phases. Said treatment cylinder has one end (B) that is hermetically closed, and on the other end (A) supports a sleeve (C) that consists of a thick-walled rubber disk (4) which on its flat sides is covered by thin-walled, highly elastic rubber membranes (6, 7). The rubber disk and the rubber membranes are provided with openings (5, 8, 9), while the diameters of the openings (8, 9) of the rubber membranes (6, 7) are smaller than the diameter of the opening (5) of the rubber disk (4) so that during pressure changes in the treatment cylinder (1) the rubber membranes (6, 7) adapt so to the form of the extremity (E) to be treated that they create a sleeve effect and close off the treatment cylinder (1) at the end (A) in such a way that the intensity of the pressure variation can be achieved and kept constant during a specific time period without having to inflate the sleeve (C). This solution prevents for the entire duration of the treatment the venous return to the heart from becoming blocked.
Abstract:
A nozzle sleeve (1) contains supply channels (2), feeding channels (3, 5, 22, 24), concentric channels (4, 6), tangential channels (8) and a ring-shaped channel (7), as well as a core (13) which covers the various channels, so hermetically that they form ducts into which a liquid flows and is pushed in a predetermined direction of rotation into the large concentric channel (4), then flows in the opposite direction of rotation into the small concentric channel (6) and finally flows once again in the predetermined direction of rotation through the feeding channels (5) and reaches a ring-shaped channel (7) from where it is sprayed out through the bore (9) of the nozzle sleeve (1). The changes in the direction or rotation cause turbulences which represent a braking force for the liquid flowing under pressure. The intensity of this braking force is directly proportional to the liquid pressure, so that the rate of flow per unit of time is held at least approximately constant.
Abstract:
A regulator is housed in the expulsion channel of an aerosol container inside which there is a product that is to be dispensed, this product being subject to an expulsion pressure originating from a compressed gas, the said regulator comprising a flexible disk (6) and a rigid disk (7), the latter presenting a protrusion (8) with grooves (9), and further comprising a sealing disk (12) with a central bore (13), and further comprising a nozzle (16). With the flexible disk (6), the grooves (9) in the rigid disk (7) form ducts for the expulsion of the product, and are oriented so as to form tangents to the circumference of the axial duct (10) of the rigid disk (7). This arrangement of the component parts creates turbulence effects in the flow of expelled product, and these effects are utilized to regulate the flow rate at which the product is expelled.
